The Mechanism and Structure of Solenoid Valve
What are the types of solenoid valves? Tracing the history of the development of the solenoid valve, so far, it can be divided into three categories according to its mechanism. These are direct-acting type, distributed direct-acting type, and pilot type. And according to the differences in the structure of the valve flap, materials, and mechanism, they […]
Read moreWhat are the Effects of the Coating on the Valve Surface?
Generally speaking, cast iron and carbon steel valves are usually painted with different types and thicknesses of paint for good protection. Sanitary valves are generally used for the transportation of water, oil, steam, etc., and are in direct contact with the metal surface, thus prone to serious corrosion under the action of oxygen. Coatings are generally […]
Read moreTop 6 Precautions to Take When Installing Balancing Valve
What is the purpose of a balancing valve? Balancing of heating and cooling systems is performed to ensure that the correct amount of water is present at all consumption points. Balancing is carried out by building balancing valves into the system, thereby adding adjustable resistance. What are the top 6 precautions to take when installing balancing […]
Read moreFeatures of the Valve Manufacturing Process
Valves seem like fairly uncomplicated equipment in the machinery industry, right? They simply open and close to start and stop the flow of fluids and other mediums. They must be fairly easy to manufacture, right? When you take a closer look, you’ll find that every residential and industrial pipeline system would immediately fail without functioning […]
Read moreWhat Does the Operating Condition of Sanitary Valves Depend?
The working condition of the sanitary valve depends on many factors, including working pressure and working temperature of the medium, variation of pressure and temperature, driving mode, the installation position of the sanitary valve, service cycle, etc. Working pressure and temperature Generally speaking, the higher the pressure and temperature of the sanitary valve, the worse the […]
Read moreThe Causes Leading to Damaged Valve Sealing Surface
Mechanical damage: There will be scratches, bumps, crushes, and other damages during the opening and closing of the sealing surface. Between two sealing surfaces, under high temperature and high pressure, there will be mutual penetration of atoms, resulting in adhesion. When the two sealing surfaces move along each other, they’re prone to be torn apart […]
Read moreWhat is a Hydraulic Control Valve Mechanism?
What are the functions of the hydraulic control valves? Hydraulic control valves are used to adjust the flow rate of hydraulic fluid in a hydraulic system. These valves have a port that is able to be adjusted so that the flow area may be changed to provide an alteration in the flow rate through the […]
Read moreWhat Are the Anti-corrosion Methods for Sanitary Valves?
Coating The coating is the most widely used anti-corrosion means, especially in sanitary valve products is an indispensable anti-corrosion material and identification sign. The coating is usually made of synthetic resin, rubber slurry, vegetable oil, and solvent, covering the metal surface, insulating medium, and atmosphere, achieving the purpose of anti-corrosion. The coating is mainly used in […]
Read moreCommon Failures of Automatic Valve
Four common failures associated with automatic valves are found at a high frequency in poorly performing control loops. These are Dead band, Stiction, Positioner overshoot, Incorrect valve sizing, and Nonlinear flow characteristic. Let’s take a closer look at each of these problems. Failure one: the valve is blocked up. The reasons are: 1. The control channel […]
Read moreFAQs in Using Valves
1. Why is the sanitary double seat valve easy to oscillate when working? For single-core, when the medium is an open type, the valve stability is good; when the medium is a closed type, the valve stability is poor. The double seat valve has two spools, the lower spool in the flow closed state, and the […]
